1\ ORNEY To all lwhom it 'm ay concern Be 1t known that I, PIERRE BOUERY, a citi- ","izeliliQ :the United States, residing 'at' Vea' verville` in the-county of Trinity and State California, have-,invented new and useful ,Improvements inr l\Iining-Sluices, of which .the following is aspeciication.

Ibis .invention relates to improvements V4in mining s luices, and particularly pertains to improvements in that type Aof mining sluices shown in Patent No. 1,036,430, issued to meAugust 20, 1912.

It isthe general object of this invention to .provide a mining sluice for the purpose of saving valuable `and. precious minerals, while Y allowing Ithe rocks, boulders, and various heavy materials to travel. down the'sluice ,-escapegl and in which a series of horizontalbars are disposed transversely of the sh'liee.,.a`v short distance above the bottom thereof, tov form a ,grating or grizzly.

The principal object of'this invention is to` providea means for detachablv mounting bars of the grizzly in the sluice box so that thev m'av be removed and interchanged when worn or broken, and to provide means b v which the bars ma)7 be interlocked and secured'in place` to prevent. their beingmaliciously' removed.

Other objects will appear hereinafter.

The inventionprimarilv resides in a series Vof horizontal transverse bars adapted to be rlhe'inventi'on further consists of the parts and4 the constructionand combination ot parts as hereinafter more fully described and claimed, having reference to the accom-l panying drawings, in whichc .E

Fig. 8 is a section on the line c--c of Fig. 5. F 1g. 9 is a detail perspective of a modified form of the interlocking joint. a further modification 'ofthe interlocking joint. `V

In the. d awings the sluice is'shown as hav ing a fiat bottom A and approa'imatetv7 vertical sides B, which may be supported bv stout sills or vertical timbers in the usual manner. Extending transversely across the bottom A are wooden ritlles f2, which are made of anjyY thickness and depth. to form the necessary interspaces for the reception of material to be saved, and supported upon the tops of these riles are. iron barshthe construction of which is particularly shown iu Figs. 3 and 6; the bars 3 being;r preteral'ily T-shaped in cross-section and having their ends terminating in verticali)v extending ribs. or projections 4. rThe ribs or projections ft may be cylindrical in horizontal section with vertical walls and an enlarged offset portion 5 at their lowei` ends as shown in Fig. 3; or ma)7 be conical. as shown in Fie. 9: or in the shape of a dove-tail as shown in Fig. l0.

The barsl are designedto be disposed transversely across the center portion of the sluice and spaced a uniform distance apart; spacingT webs G and 6 being formed on the verticalfportions of the bars 3 and extending at right an g'lcs thereto. intermediate the ends of the bars, which are adapted to engage the ends of correspondingr webs on adjacent bars to center the bars and space them equal distances apart. The outer end of the web G is formed with a verticall)1 extending concave tace. while the outer end of the web (3 formed with a convex` face which is adapted t0 extend into the. concave tace on the adja- -cent web, assho vn in Fig. 2.

Iadapted to beengaged 4with the vertical ribs Fig. 1e is o r projections 4 on the ends of the bars`3, f

to form an interlocking connection betweenthe transverse bar: andr the longitudinal bars 7. The bars 'l' Vare designed to extend `parallel with thesides B of the sluice, and are spaceda short distance therefrom.

Formed onthe onteriaces of the longitudinal bars 7 4are."vertical notches 9, which fare adapted to receive the vertical web por- Fig. 'T is a section on the line bfb of Fig, 4; tions of short filler :bars 10, which extend sockets 12 on the bars 7.

proximately the full width'of the sluice,v -and have their outer lends engaged in the notches .of the bars 11. The transverse locking bars 14 serve Ito hold th'e longitudinal locking bars 7 in. their interlocked engagement with the bars 3, and are provided with-v laterally extending flanges 15, which project over the projections 13 and extend over the ends of the bars 7, to prevent the latter being raised, and to close the jointbetween the projections 13 in the bars 14 and the The locking bars 14 and the bars 10 are connected to the sides B of the sluice by meansA of angle irons 16,'

or other suitable members, which are bolted or otherwise attached to the sides of the sluice and extend over the ends of the bars 14 and 10, as shown in Fig. 1.

By vthe construction hereinbefore described, in order to obtai'n access to the material bet-Ween the ritlles 2, it is necessary to remove the angle irons 16 from the sides of the sluice, lift the filler bars 10 and the locking b ars 11' out of engagement with the bars 7 and 11, and disconnect the longitudinal "locking bars 7 from the transverse bars 3 by lifting the former clear of the latter.

The grating or grizzly formed by the transverse bars 3 and 10 and interlocked with the locking bars 7-14 and'1l, is con- 4structed `in sections of any suitable length,

and is adapted to be removed from the sluice and renewedl as occasion mayrequire;

By employing the interlocking connections between the ends of the bars 3 'and the bars 7, and providing a similar connection between the ends of the bars 7 and the locking bars 14, the use of bolts or similar securing elements is dispensed with; this construction forming a rigidinterlocked struc-v ture which will be heldin place in the sluice by side rails 16 detachably mounted on the sides of the sluice. 1

It will be seen from the foregoing, that The 'v .the bars 3 will be held in jr .p1ace on Athe riles 2. by the bars 7 which must be inoved vertically' in and out of engagement with the bars A3,'a`nd that the bars 7 are heldin engagement with the bars 3b the bars 14. which must be movedvertical yin 'and out of connection with the'bars 7. Iij, ,.fo1lowsthat by securing-the ends of the-bars 1 4 l against upward movement,-the barsf7 and:

a sluice,v of a;

series of spaced T-bars, vertical .projections Y on the endsof said bars, bars formed with notches adapted to be placed over ,thelprojections of theT-bars to engage the latter and hold the T-b'ars against u ward move-:

ment, and transverse locking ars engageable' with .the ends of the notchedibars to Y i hold the latter in -place on the T-bars.

2. In a sluice, a series of spaced transverse T-bars, a pair of longitudinal parallelbars; means for connecting the longitudinal bars to the ends of the .T-'bars from above to hold they latter against movement, transverse locking bars adapted to'be .engaged with the ends of the longitudinal bars from above, and means for securing the ends of the loking bars to the'sluice.

3. A grating for sluices, comprising transverse bars, projections on the ends of said bars, spacing members on the sides of the bars engageable Vwith spacing members on adjacent bars, longitudinal bars having notches engageable with the projections' on and projections shaped to prevent the transverse bars vbeing lifted out of engagement -the transverse bars from above, saidfnotches Y ,with the longitudinal bars, transverse locking bars, projections thereon engageable I with notches on the longitudinal-bars from above, flanges on the transverse lookin bars' -projecting overtheends' o f the longitudinal bars, and means' for securing, the transverse locking bars to a sluice. l
